Scope

This Part of GB/T 20975 specifies the method for the determination of hydrogen
content in solid aluminum and aluminum alloys by heating extraction-thermal
conductivity method.
This Part applies to the determination of hydrogen content in solid aluminum
and aluminum alloys. Determination range: 0.05 μg/g ~ 1.0 μg/g.
Note: This method only performs inter-laboratory test on the specified
measurement range. However, the laboratory can extend the
measurement range of this method through experiments such as method
sensitivity, precision and bias in method validation.
